OUTCAST,
Yes I totally agree with you on the "type of the kit".
For this discussion we are not talking about a scale model P-51 with authentic rivets and gun soot etc.
Let's take 2 very popular ARF's and compare building vs. ARF for discussion sake:
1) Avistar trainer ARF vs. similar high wing trainer....
2) AW 29% Edge 540 kit vs. the new AW 31% Edge 540 ARF...
And I couldn't agree more on the 90% done and 90% remaining remark
